Observe que nós declaramos o tipo de `current_user` como o modelo Pydantic `User`.

Isso nos ajudará dentro da função com todo o preenchimento automático e verificações de tipo.

/// tip | Dica

Você pode se lembrar que corpos de requisição também são declarados com modelos Pydantic.

Aqui, o **FastAPI** não ficará confuso porque você está usando `Depends`.

Comme ce fichier se trouve dans le même package, vous pouvez utiliser des imports relatifs pour importer l’objet `app` depuis le module `main` (`main.py`) :

{* ../../docs_src/app_testing/app_a_py310/test_main.py hl[3] *}


… et avoir le code des tests comme précédemment.

{* ../../docs_src/security/tutorial002_an_py310.py hl[25] *}

## Obtener el usuario { #get-the-user }

`get_current_user` usará una función de utilidad (falsa) que creamos, que toma un token como un `str` y devuelve nuestro modelo de Pydantic `User`:
